water pressure drop

Shower has been working fine, no other changes on the hot/cold system and now after a few minutes the water pressure at the shower head drops. The temperature control is fine and even as pressure drops it remains a constant temperature? Any suggestions appreciated,

thank you

There is nothing in the valve itself that should cause pressure loss.

Check the hose if it is old, then the inner part of the hose could be collapsing and restricting the flow when the water warms up.

 

Other than that the only thing I can suggest is to fit a service kit to the valve and when you have the valve dissembled give the pipe work a flush out

 

 

This will take two!

 

If your valve is recessed pack an old poly bag round the valve to divert the water into your Bath / shower tray then turn the hot and cold valves on one at a time and allow the water to flush through for about 15>20 seconds.

 

The person who is helping you should watch that the water is not going anywhere that is going to do any damage also they should watch that the amount of water coming from the hot and cold they should be roughly the same.
